MarsSeed [1] filed a deletion request for qt5-multimedia-plugin-ffmpeg [2]: Not needed by any packages. One-person project started and discontinued in 2021. [a] - In total it has 20 commits. [a] - 0 issues ever, 0 PR's. - no documentation. - only Qt5 - developed upon ffmpeg 4.1 and ffmpeg 4.4 only - no automated building and testing whatsoever - zero test code - readme hints that it was developed on Windows only - weird architecture: supports QtAudioOuput for audioplayback backend, but prefers SDL2 (why?) Arch repo's qt5-multimedia relies on gstreamer, but through gst-libav optional plugin, it can use ffmpeg. Packaging broken but no one complained: - cannot be built because of missing makedepend 'qt5-tools' - source link is changeable file (GitHub 'main' branch zip file) - no source checksum checking Package has no comments or votes. Seems it is not useful to any user. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/qt5-multimedia-plugin-ffmpeg/
